Casabrews CM5418 Review: Can a Budget Espresso Machine Make Great Coffee?

Introduction

The Casabrews CM5418 costs just over one hundred dollars and challenges the common belief that budget espresso machines cannot produce quality shots. This compact, stainless steel entry-level machine has proven durable and capable over extended use, raising the question of whether affordable espresso equipment can deliver impressive results with the right approach.

Build Quality and Design

The Casabrews CM5418 features a compact footprint and stainless steel housing that feels solid for its price point. The control panel is straightforward with no intimidating settings, making it accessible to beginners. The brew head uses a standard 51-millimeter size, common across machines in this price range.

The machine includes a 51-millimeter portafilter equipped with pressurized baskets capable of holding up to 15 grams of coffee. The basket installation uses a simple knob-and-groove alignment system, though this design does not facilitate easy swapping of alternative basket types. The plastic spout at the bottom of the basket is functional but basic. Despite its entry-level positioning, the machine has demonstrated reliable performance over two years of regular use.

Understanding Pressurized Baskets

The stock pressurized baskets, also called double-wall baskets, feature a single hole at the bottom that forces coffee through a restricted opening. This design creates crema-like microbubbles on the shot surface, producing a visually appealing result even with imperfect grind size or pre-ground coffee.

This beginner-friendly approach means you can pull a decent-looking shot without precise puck preparation or dialing in. The machine includes pre-infusion, which wets the coffee puck before extraction to promote even brewing. A pressure gauge provides feedback on shot progression. The single-hole steam wand, while not powerful, suffices for home milk steaming and can also dispense hot water for Americanos.

Pulling Your First Shot

Using 15 grams of beans ground on the coarser side, the pressurized basket prevents choking the machine. The included plastic tamper handles basic puck compression. The machine begins with a few seconds of pre-infusion before golden liquid flows smoothly into the cup. The shot pulls quickly due to the coarser grind, producing a visually acceptable result that works well as a base for Americanos or milk-based drinks like lattes and cappuccinos.

However, drinking the shot straight as espresso reveals limitations: the flavor tastes bland and bitter, with room for improvement. This is where upgrades become worthwhile.

Key Upgrades for Better Shots

An espresso grinder makes the most significant difference. You do not need a high-end model; an entry-level burr grinder or quality hand grinder works well as long as it can grind fine enough for espresso. Smaller step adjustments provide better control when dialing in shots.

The real game-changer is swapping the pressurized basket for a non-pressurized one. Unlike the stock basket, which relies on its design to create resistance, a non-pressurized basket puts all focus on your coffee puck and grind size. You will need to dial in your grind more carefully to achieve optimal flow and extraction, but the results are significantly better. Note that non-pressurized baskets do not fit the stock portafilter, so you will need to purchase a 3-tab portafilter separately.

A solid metal tamper replaces the plastic one included in the box, delivering more consistent results when compressing the coffee puck. With these upgrades in place, aim for 30 to 36 grams of output within 25 to 30 seconds. If your shot pulls too fast, grind finer; if too slow, grind coarser.

Puck preparation becomes more important with non-pressurized baskets. After transferring grounds into the basket, use a WDT (Weiss Distribution Technique) tool to stir and distribute grounds evenly, preventing clumps and uneven density that cause channeling during extraction. Once everything is evenly distributed, tamp firmly and consistently.

The difference is dramatic. The coffee now displays authentic crema instead of pressurized bubbles, with a smoother texture and richer flavor notes like nuttiness and chocolate. Freshly roasted beans, a decent grinder, and non-pressurized baskets elevate shot quality substantially.

Steaming Milk and Milk-Based Drinks

The machine handles milk steaming adequately. Tilt the steam wand to approximately three o’clock so it sits just above the milk surface. You should hear a tearing sound initially, then lower the wand slightly to create a vortex while steaming until the pitcher is too hot to hold comfortably.

Bubbles may be larger initially but tapping and swirling the pitcher smooths them out. Alternative milks like oat milk are trickier than dairy milk but still manageable. Even with the single-hole steam wand, simple latte art like a tulip design is achievable with practice, demonstrating that the machine supports milk-based drink development.

Conclusion

The Casabrews CM5418 proves that budget espresso machines can produce impressive results when paired with the right upgrades and technique. With a better grinder, non-pressurized baskets, a quality tamper, and proper puck preparation, this affordable machine delivers shots that rival machines at higher price points. For anyone entering the espresso hobby on a tight budget, the CM5418 offers a practical entry point that does not compromise on potential quality.
